"Compared to the size of the universe we are small and insign..." — Rebecca Ryder quote meaning

Compared to the size of the universe we are small and insignificant, but you’ve got to keep it in perspective. We’re lucky really, I mean think of the odds of you existing at all. The universe went through a billion acts of chance that led to you being conceived, millions of chemical reactions occurred just to make you, you. Think of all the potential people that could have been but didn’t get the chance. Look around. The mere fact that the universe is so large and yet we are able to be here like we are is amazing. We are unlike any other planet or species in the universe. Don’t look at it all and think we’re insignificant. We’re the equivalent of someone finding a diamond the size of a grain of sand on a beach the size of Mars. We are small, but we ARE significant.
